I have a Sanyo tv ( model #DS19330 ) and using a Sony remote to operate it. I am trying to restore channels 14-69 by scrolling through the channels with the remote. I can punch all channels in by...

It sounds like that the TV was set to skip certain channels. You need to rescan for channels or manually edit the channel list. To manually add channels, press Menu on the TV (or the equivalent key on the Sony remote if you found a code that works). Then use the Up/Down arrows (channel change keys) to select Ch Scan Memory + . Then enter the number of the channel (numerically or up and down arrows). Press + (volume + key) to change the setting from Deleted to Added or vice versa. Since you do not have the original remote, I'm not sure if the Sony remote will match the Reset key of the original remote. Unfortunately without that key being pressed twice, you can't reset the entire channel list and cause the channel search to begin automatically.

The manual for the DS19330 TV is here: . (I'm assuming you haven't recently added cable after only receiving only OTA signals. If you have changed inputs like that, you need to go through the menu and change the source.) Menu > Cable or Air .

I hope this helps.

I can only get channels 600 through 900 which I have never see before.I cannot get regular channels or cable channels.It is not a flat panel t.v.Q1435A is the model number

Hi -

If you have a cable TV line connected directly to the TV, an antenna or a cable box connected by coaxial cable, I would suggest running the automatic channel scan (AUTO-PROGRAM) again:

1. Press the AV key on the Advent remote control repeatedly until TV is displayed in one corner of the TV screen. If you don't have the Advent remote, use the TV/AV button on the front of the TV.
2. Press the MENU key on the advent remote or the front of the TV to open the on-screen menus.
3. Use the CH+/- keys on the remote or on the front of the TV to highlight PRESET then press VOL+ to select.
4. Use the CH+/- keys on the remote or on the front of the TV to highlight ANTENNA then use the VOL+ key to select either AIR (for antenna) or CABLE.
5. Use the CH+/- keys on the remote or on the front of the TV to highlight AUTO-PROGRAM then press the VOL+ key to start the automatic channel scan.

Once the channel scan is complete, the TV should automatically return to viewing the first channel found during the scan. Do not press the MENU key during the scan or the scan will not complete.

If you are using a cable/satellite receiver and it is connected to the TV by any means other than a coaxial cable, you do not need to run the channel scan. You should simply select the correct AV input using the AV key on the remote or the TV/AV key on the front of the TV (see step 1 above).

If you have done all of the above and you are still unable to get the channels on your TV, please post back for further assistance. You can reply to me by clicking on "Add a Comment" below your question. Please let me know whether you are using a direct cable line, antenna or cable box, etc.

My brighthouse remote can turn my tv on and off but not change channels

The remotes have several device keys at the top of the remote. They have abbreviations like "VCR", "DVD", "TV", "CBL". By default some actions are locked into a specific key. By default, the volume buttons will always control the TV volume and the channel buttons will always change channels on a digital box.
If you have a digital box, and the channels wont change, the default locks might have been removed. Consult the instruction manual that came with the remote and re-lock the buttons to the correct device key. Otherwise you will need to press the "tv" button when trying to change volume and the "cbl" button when trying to change channels.
If you do NOT have a cable box and are just simply trying to use the universal remote as a primary remote, you will need to unlock the global channel lock. Consult the manual for the remote or check online for the remote guide. The Company which makes the remotes is called Universal Electronics and you can find digital copies of their manuals on the Brighthouse Websites.

Westinghouse LTV-32w4 HDC - adjustment buttons unresponsive, volume drop, etc.

plug your cable connection to a vcr "in" then run a seperate cable cord from the vcr "out" to your television (which should be on channel 3 or 4) depending on your vcr setting and use the vcr to control the channel so when your westinghouse freezes and becomes unresponsive you could still change the channel and so on through your vcr and tv acts like a monitor works for me. N.B be sure to set the volume and so on before it freezes which could be like a 1min window from turning your tv on
